IntroductionGrade S50C carbon steel is a high quality medium carbon steel&comma;which adopted by the furnace&comma; open-hearth&comma; or oxygen converter steelmaking manufacture full killed steel having a uniform microstructure features&period;

The carbon composition of this kind of steels is over 0&period;4&percnt;&comma; and it has good wear resistance&comma; high tensile strength&comma;easy for deformation and crack when quenching&comma;so that quenching for this material is very importance and it must quick cooling after tempering in order to avoid temper brittleness&period;

It can improve the machinability of these carbon steel through spheroidizing&period;He steel is usually tempered to hardness 19~22HRC&comma; to increase its cutting performance
